Introduction / Table of Contents Step One An ultrasonic sound wave is pulsed from the base of the transducer. The sound wave reflects against the process medium below it. The sound wave energy is returned to the transducer. The microprocessor based electronics measures the time of flight between the sound pulse generation and its receipt.

Introduction Step One REFLECTIVE TECHNOLOGY Condensation is the most common variable in liquid level applications. Condensation attenuates the acoustic signal of ultrasonic sensors with horizontal transducers, weakening their signal strength and signal to noise ratio by up to 50%, and substantially reducing their measurement reliability. At the core of Reflective Technology is a simple fact.
PRODUCT. This manual includes information on the NEO-7 series Ultrasonic Level Transmitter from KOBOLD INSTRUMENTS. Please refer to the part number located on the switch label to verify the exact model configuration, which you have purchased. User’s Responsibility for Safety: KOBOLD INSTRUMENTS manufactures a broad range of level sensing technologies.
Section 6 contains information about the sensor’s electrical wiring and power requirements. Note: When configuring NEO-7 series, choose either the NEOCal software or Push Button method. Either method will accomplish the goal of sensor configuration. Changes to the configuration can be made using the alternative method.
Getting Started Step Two NEOCAL SOFTWARE VS. DISPLAY CONFIGURATION ® NEO-7 can be configured using either the free NEOCal software and USB Fob or with the internal display module. Either method will accomplish the goal of sensor configuration. Changes to the configuration can be made using the alternative method.
Getting Started Step Two UNDERSTANDING SENSOR HEIGHT (HEIGHT) This is a critical setting for NEO-7. Sensor Height (SH) defines the location of the sensor from the bottom of the tank. The value must take into account the shape of the tank and any risers, fittings, structures or extensions associated with the tank or the installation (see examples below).
Getting Started Step Two UNDERSTANDING FILL-HEIGHT (FILL-H) This is another critical setting for NEO-7. FILL-H (Fill-Height) defines the location of the highest point in the tank where the sensor will read level changes. When the level rises above FILL-H, the sensor will read full (as long as the level does not enter the dead band).

Getting Started Step Two Example #4 – Cone Bottom Tank Tank G and Tank H are both vertical tanks that are being supported above ground level with tank stands. The location of the Sensor Height (Tank G - bottom of tank or Tank H – ground level) will influence the FILL-H setting.
Getting Started Step Two SENSOR OUTPUT TO LOCAL DISPLAY/CONTROLLER NEO-7 outputs a 4-20 mA signal to a local display/controller or to remote devices such as PLCs, SCADA, DCS or other displays/controllers. The 4-20 mA signal is set relative to the Sensor Height and Fill-Height settings. These settings create an operational range that can be translated into a level reading in defined units (i.e.
STEP 1 – INSTALL NEOCAL SOFTWARE NEO-7 is configured through NEOCal software, a PC software program. The NEOCal software is a free download from KOBOLD Instruments’s website. You must download and install the NEOCal software prior ® to plugging in the USB Programming Fob (NEO-PFOB).
Wiring to Fob (using NEO-PFOB) NEO-PFOB USB Wiring is identical for all NEO-7 Series – Use only the Red, Black, Green and White wires. The maximum cable distance between the computer and NEO-7 is 15’. This only applies for configuring the NEO-7.
Configuration Using NEOCal Software Step Three STEP 2 - MEASURE THE TANK Measuring the tank is one of the most important aspects in configuring the sensor. When measuring the tank, take into account the location of the sensor with respect to fittings, risers, dome tops and bottoms, and identify where the measurements are taken from the sensor.
Configuration Using NEOCal Software Step Three With NEO-7 connected to your computer, open the NEOCal software by clicking on the software icon. Follow steps 3-6 to configure the transmitter. Click “Help” in the lower right hand corner and open the help menu of instructions on the NEOCal software.
Configuration Using NEOCal Software Step Three STEP 4 – DIMENSIONAL ENTRY: Distance Mode (default): Output of sensor is based on the distance (height of liquid) in the tank. Any change in liquid level will reflect linearly to the current output. Note: Most applications will fall into this category.
Configuration Using NEOCal Software Step Three STEP 5 – TANK LEVEL CONFIRMATION: Verify the Height Units, Sensor Height & Fill-Height. All values were calculated in the previous Dimensional Entry window. To adjust these settings, click on Volumetric Modes. STEP 6 – WRITE TO UNIT: This NEOCal software operation uploads configuration into the sensor.
Configuration Using Display Step Four NEO-7 can be configured before installation. The transmitter features non-volatile memory, so any setting configured before installation will not be lost when the switch is powered down. To configure, follow the steps below: Note: When configuring 1.
Configuration Using Display Step Four TOP-LEVEL MENU The TOP-LEVEL MENU will continue to scroll through the items listed to the right until the OK button is pressed. To return to the Normal / Operational mode of NEO-7, press OK while RUN appears in the display.
Configuration Using Display Step Four STEP 3 - SETTING THE HEIGHT (SENSOR HEIGHT) 1. In TOP-LEVEL MENU mode, select TANK. 2. Select HEIGHT. 3. Using the UP and DOWN buttons, set the HEIGHT of the tank (transducer face to the bottom of the tank). 4.
Configuration Using Display Step Four STEP 4 - SETTING THE FILL-H (FILL-HEIGHT) 1. In TOP-LEVEL MENU mode, select TANK. 2. Select FILL-H. 3. Using the UP and DOWN buttons, set the Fill Height (FILL-H) of the tank (max. level of liquid to the bottom of the tank).
Configuration Using Display Step Four STEP 5 - HOW TO SELECT FAIL-SAFE CURRENT OUTPUT (LOST) In the event the sensor does not receive an echo, the Fail-Safe Current Output or LOST setting can be set to output a current of 4mA, 20mA, 21mA, 22mA or Hold (last known value). During fail-safe, the display will read LOST.

Wiring Step Six ANALOG OUTPUT (4-20 MA) The analog output of the NEO-7 is a loop powered 4-20 mA control circuit. The typical way to use this feature is to connect a positive supply to the (+) input and to sense the current flow out of the (-) output. WIRING DIAGRAM –...
Wiring Step Six WIRE CONNECTIONS (+) Power & (-) Return: (+) Power and (-) Return leads are for connection to a 24 VDC power supply or to a 4-20 mA loop power source. The (+) and (-) wires can be extended up to 1,000 feet using a 22-gauge or larger wire.
To access the terminals, gently remove the display from the housing. When wiring is completed, restore the display to the housing and replace the cover. The NEO-7 series can operate without the display. When wired and powered correctly, the sensor will continue to provide a proportional 4-20 mA signal.

This function does not influence the current output, just the display on the sensor. 1.
Display Appendix Section Eight HOW TO REVERSE THE CURRENT OUTPUT The factory setting for NEO-7 has 4mA set at the bottom of the tank and 20mA at the top. If the application requires this output to be reversed (20mA at bottom and 4mA at top), then use the REV MA setting to reverse the current output.
Display Appendix Section Eight HOW TO SETUP THE START-UP POWER (STRTUP) During the window of time between when power is first applied to the sensor and the sensor acquires the level reading, the output current can be preset in order to avoid any false alarms during this window. The options for start-up are 4mA, 12mA, 20mA or 22mA.
